Specification of Letters Patent.

Patented Oct. 8, 1912.

Application filed February 20, 1911: Serial No. 609,612.

To all whom 2'2 may concern:

Be it known that I, Mourns ll. Poet, a citizen of the United States, andresident of the borough of Brooklyn, city of New York, in the county ofKings and State of New York, have invented certain new and usefulImprovements in TypeJVriting Machines, of which the following is aspecification.

My invention'relates to ribbon mechanisms for typewriting machines andone of its objects is to provide a key controlled throw-varying device,for varying the widthwi'se portion of the ribbon presented to the typesby the ribbon throwing or v1- brating mechanism, in combination with astrmwarying mechanism controlled by a key separate and distinct from thekey for vary ing the throw.

Another object of the invention is to so combine the key controlledstop-and-throwvarying IllCCllftIl'lSIDS that the throw-wirying mechanismcannot be re-sct by its key in the features of construction,combinations of devices and arrangements of parts hereinafter describedand particularly pointed out in the claims. v y

While my invention may be adapted to various styles of writing machines,the pre ferred embodiment of the invention is shown herein in connectionwith a No. 10 Remington visible tyliewriting machine, Figure 1 being aside elevation of said machine cmb'odymg my invention, partsbeingomitted and parts broken away; Fig. 2, a fragmentary perspective view,taken from the rear, of the ribbon mechanism; Fig. 3, a rear view of vpart of the ribbon mechanism taken in vertical section; Fig. 4, avertical sectional view taken tn :1 plane represented by the lineIII-wit in Fig. 3 and looking toward the right; and Fi s. 5 and 6,perspective views of a modifiet construction of ribbon vibrator.

As appears from Fig. 1, the main frame of the machine comprlses a base1, corner posts 2 and atop plate/3, and supports printinginstrumentalities comprising type bars at pivoted on hangers o securedto a verti -al stationary segmental support (3, each type bar, beingconnected through a link 7, lever 8 and link 9 with a key lever 10having a fulcrum 11 and a restoring spring 12. The type bars aresegment-ally arranged and c0- operate with the front face of a rotaryplaten 13 supported on a vertical shifting platen frame l-Ll. connectedby links 15 to a carriage lruck'lti which coiipe 'ates throughanti-friction rolls 1'? with fixed trackways 18 above the top plate Theplaten carrier or carriage comprising the truck and platen frame isimpelled leftward by a carriage power or spring drum 19 with which it isconnected by a-band 20. Leftward step-bystep movements of the carria eare controlled by escapement devices (hot shown) which are connected bya link 21 with a crank arm 22 on a rock shaft 23 provided near its endswith crank arms 24 from which are suspended by links or arms 25 a.universal bar 26 underlying the set of key levers l0 and being operativethereby. The platen and platen frame are adapted to be shifted on thetruck through a shift rod 27 which provides a track for a roller 28mounted on the platen frame. The shift rod is connected .at its ends byvertical arms 29 with a shift frame bar 30 having at its ends dependingarms 31, pivoted to shift key levers (not shown), said levers.operatingto shift the frame comprising the bar 30, rail 27 and uprights 29 upwardand downward to shift the platen and platen frame correspondingly.

Vertically disposed ribbon spools of which the left-harul one is shownand designated as 32, are arranged below and forward hf the platen, eachribbon spool being mountedon a shaft 713 which carries a beveled gear34:, said gear being, connected with the spring drum by a train ofmechanism comprisim intermeshing beveled gear wheels 37 an 38. Thedriving shaft/36 is shiftable endwise to bring one or another of thepinions 35 into mesh with its cooperating beveled gear 2-H, thusalternately conncetingthe ribbon spools with the driving shaft. andrevcrsing the direction of longitudinal feed of the ribbon. I

The ribbon designated by the nmeral 3.) wound on the spools 22 andguided upward, inward and rearward toward the printingpoint. \Vhile asingle-color ribbon may be employed, my invention. is especiallyapplicable to ribbons having printing fields of differentcharacteristics, and accordingly the, ribbon 39 is such a ribbon, itbeing divided lon itudinally into printing fields a and b of dlfferentcharacteristics, as

v 6 colors. Opposite the printing point the ribor members 43 and 44, themember 43being pivotally connected to the'vibrator at 45 and .15 beingitself pivoted at 46 to-the lever part 44, which is fulcrumed at 47 on afulcrum bracket 48 on the frame plate 42. The lever parts 43 and 44. aremaintained in normal relationship by devices comprising a lever 49'fulcru'med at 47 co-axially with the 52 fixed at 53 to the shift bar 30."The norlever part. 44. The lever 49 is connected through a link 50 withthe tail 43 of the lever 43 and the opposite armof said lever 49 ispivotally connected at 51 with an arm mal lower case position of thelever parts is illustrated in Fig. 2. At printing operation the twolever parts are operated as a single member without substantial changeof relationship; but when the platen is szshifted it operates throughthe arm 52, lever 49 and link50 to alter the normal relation-- ship ofthe lever parts 43 and 44, the part 43 turning on the pivot'46to'liftthe vi,-

brator and ribbon to a new normal position corresponding withthefshifted position of the platen. From its. shifted position'the leverpart 43 will again be operated as before, together with the lever part44 at 40 printing operation. During the shifting movements of the leverpart 43 due to the platen shift the lever part 44 will remainunaffected," Theseparts 43 and 44,-although in themselveslevers, have.been designated 45 aslever parts since together they are comprised inthe operating lever as a whole, which operating lever is fulcrumed at47, is connected at 45 to the vibrator and is connected at'.the.oppositeside of. the fulcrum' to actuating devices which comprise a stud 54engaging in a slot 55 in the lever part 44, said stud being fixed to theupper endof an actuating. link 56 off-set rearwardly as indicated at 56to an arm 58 on 55 the rock shaft 23. It will be understood that atprinting operation the universal bar 26 is actuated, rocking the shaft23 and I vibratin the link 56, said link in turn actuating he operatinglever 43-, 44 which vi- 60 brates the vibrator 40 and raises and lowersthe ribbonfirst tocover the printing point toreceive the type impressionand then to lower the ribbon to expose the imprint on the paper."

The stud 54 is settable at different points ,lengthwise of the slot 55tovary' the extent part by a screw 60 on the bracket 48. The

shift frame 59 is formed with a downward extension 59 provided with aslot 61 in which the stud 54 en ages. The tail or extension 59 of theshi t frame is offset rearward and extended laterally, being pivotallyconnected at 62 with a lever fulcrumed at 64 on a bracket 65 screwed orotherwise securedto the periphery of the type bar segment. The off-setarm of the lever 63 is pivot-ally connected at 66 with a crank arm 67secured to the rear end of a rock shaft 68,'said rock shaft hearing atits rear end 'in an extension of the bracket 65 and extehding forward toa bracket 69 supported on the left-hand front corner post 2, said shaftbearing on and projectin through said bracket 69 and being provide atits forward end with a knurled finger button 70 by which the shaft mayberocked back'and forth. The rotary movements of the shaft operate throughthe crank arm 67 and lever 63 to slide the shift frame 59 back andforth. When the shift frame is slid inward from the Fig. 2 position itwill operate to shift and re-set the stud 54 and link 56 so that theywill operate nearer the fulcrum 47 of the, operating lever. The resultis that at printing operation a greater extent of throw is communicatedto the operating lever and the ribbon vibrator is lifted to a greaterheight presenting the lower ribbon field b to the action of the types.The ribbon throw-varying mechanism above described is that withwhich themachine has heretofore been provided.

In carrying out my invention 1 provide novel stop (lGXLliIQS for thevibrator actuatmg mechanism, said stop devices beihg con trolled by akey or finger piece separate from and independent of the finger piece orkey 70 which controls the throw-varying means. The novel stop devices,as herein shown, com-prise a stop member 71 which is pinned at 72 to arock shaft 73 and is provided with two radial projections whichterminate'in stop faces 74 and 75, the stop face 74 being at avgreaterdistance from the axis of rotation of 'the shaft 73 than is the stopface 75: The stop faces are ad'a ted to cooperate with the bottom face 00. lug 76 formed at. the rear end of the lever part 44.

The rock sha-ft 73 extends leftward, termipart 80 with stop extensions80 and 80.

The part 80 is engageable with V-notches 81 and 82 formed in a collar 83fixed to the rock shaft 73 to the right of the stationary I tent springto ride out of the notch 81 and bearing bracket 7 8.-

When the detent 80 is engaged with the.

notch 81 as shown in Fig. 2, the stop face 74 is uppermost and in thepath of the coacting stop 76 on the lever part 44. This relation of thestop faces corresponds with the arrangement of the throw-varying niechjI anism shownin Fig. 2 wherein the stud 54 is located to give theoperating lever the shorter of its two predetermined extents ofvibrating movement. The height of 'the stop face 74 is such that thestop 76 will contact with it to arrest the ribbon throw 0r vibratingmechanism when said mechanism'j has raised the ribbon high enough to present the ribbon field ato the type. The co acting stops 74 and 75 willoperate to prevent overthrow of the ribbon and will insure that theprinting is confined to the. ribbon field a.

Since the throw-varying and stop varying devices are controlled byseparate and "independent keys or hand d vice's there is a possibilitythat the operator, when resetting or readjusting the throw -varyi'ngmechanism might orget to correspondingly readjust or reset the stopmechanism. To guard against this possibility I provide check deviceswhich prevent the r'e-adjustment of the throw-varying mechanism untilthe stop mechanism has been itself reset. The check devices constitutemeans for insuring that the independent throw varying and stop mechanismshall be set and reset in a predetermined order; that is, the stopmechanism shall be reset first and the throw varying mechanism last. Inthe present instance the check or reventive devices comprise an arm 84fixed t0 and rising from the rock shaft 73 and having a rearwardly bentextensiol'i or stop proper 85 which lies in the path of movement of theupper arm of-the lever 63 so that the lever cannot be turned on itsfulcrum in the course of resetting the rheck 85 has been swung out ofthe way, the

only manner of accomplishing this being by w g, irning the rock shaft 73to reset the-stop mechanism. For instance, in the Fig.2 posit-ion of theparts wherein both the vibratring mechanism and the stop mechanism areset to provide for the'proper movement and arrest in printing positionof the ribbon field a, the stop 85 is at the left of the lever 63 viewedfrom the rear ofthe machine an into the notch 82, the V 8O passingslightly beyond the point of said notch and engaging with the lowerportion of the rear incllncd face thereof. It will be understood thatthe rock shaft 73 will thus be put under a slight tension which tends toturn it oppositely from the arrow-in Fig. 2. Consequently if new thestud 54 be re-adjusted nearer the fulcrum 47 (as shown in Fig. 3)v byturning the finger button 70, the lever 63 will be swung across past therear end of the stop 85, as shown in Fig. 3, and said stop willthereafter turn backward slightly until the spring-V, seats itself inthe bottom of the notch 82. This slight backward turning movementre-se'ts the stop 85 in the path of the lever 63 but at the oppositeside of said lever, as will be understood from a consideration of Figs.3 and 4. The engagement of the spring detent with the notch 82 maintainsthe rock shaft 73 in its new or reset position in which position thestop face 75 is set in the path of the stop 76 so that it will arrestthe operating lever 43, 44

when it has been given its greater extent of throw by the I'e-setactuating stud 54.

When the vibrating mechanism is arrested by the engagement of the stop 76 with the stop 75, the ribbon field b will be opposi print-in point andthe stops will pr said ribbon field from being overthrown past theprinting point. a

It will be seen that when set in the position shown in Figs. 3 and 4,the stop 85 will prevent the resetting of the vibrating mechanism in theFig). 2 position since the lever 63 will be locked y the stop 85 againstswinging back from the Fig. 3 to the Fig. 2 position. Consequently as apre-requisite to resetting the vibrating mechanism for the upper ribbonfield a, it will be necessary to re-set the stop 'mechanism by turningthe rock shaft forward slightly to permit the lever 63 to swing pastitwhen'the finger button 70 is turned, and thereafter to turn the rockshaft 73 rearward until arrested by the contact of the rear face of thecollar 83 with the stop 80". By these operations the stop mechanism willbe re-set m the Fig- 3 position and the throw-varyinginechanism alsoresetin said position.

It will be observed that the key or finger button 70 is at the front ofthe machine and the key or finger button'77 is at the left-hand side ofthe machine, so that these keys or' buttons may be convenientlymanipulatedconcurrently by the operator, one key with one hand and onewith the other, although they areseparate and independent. Thus it willbe seen that the advantages of a simultaneous manipulation ofthrow-varying or stop devices are retained while the difficultiesheretofore encountered in practice of successfully adjusting the partsof interdependentthrow-varying and stop devices to give correspondingand accurate results are obviated.

The vibrator heretofore described has the tops of the ribbon receivingslots closed and possibility of the ribbon beingthere is no thrown outofthe vibrator, but there are times when the printing portion of theribbon is thrown higher than it should be between said slots. In orderto provide for more perfect control ofv the printing portion of theribbon devices may be employed of the character shown in Figs. 5 and 6.Fig. 6 illustrates a vibrator designated as a whole as 86 and providedwith parallel up right portions 87 which terminate at their tops inspring forks 88, said forks providing closures at their tops forvertical slots 89'. The slots are adapted to receive a ribbon frame 90(shown in Fig. 5). Said ribbon frame is preferably formed of a singlepiece of sheet metal'which inc'loses the ribbon in a narrow framehaving: an opening 91 through which the types maystrike. The

frame is provided witlrforwardly. extendingangular ears .92 which areadapted to fit in the slots 89 in the vibrator,- being snapped intoplace by forcing them down between the spring forks 89, saidjforkshaving beveled upper edges and the lower faces of said forks which formthe tops ofthe slots 89 being also slightly beveled to facilitate theremoval of the frame from the vibrator VYhen. in place the frame holdstheprinting portion of. the ribbon accuratelyzini tion on the vibratorandso that theribbon passes behind the upper parts of the uprights 87.Preferably, as a matter of convenience, a sheet metal frame .90 may beprovided with each ribbon, being arranged on the outer free end of theribbon so that v when the same is to be employed in the ma chine, theribbon frame may be. readily snapped into place on the vibrator. Theribbon .frame prevents the accidental displacement of the ribbon on thevibrator and also prevents the upward displacement of the printingportion of the ribbon due to the momentum imparted to the vibrator atprinting operation.
